Temperature Monitoring

TagFinder Monitor provides continuous temperature and environment monitoring with 0.1°C precision. This guide covers the Cold Chain Monitoring solution module.

Enabling the module

Your organization admin must enable Cold Chain Monitoring under Settings > Organization > Solutions. Once enabled, it appears in the sidebar under Solutions.

Dashboard overview

The Cold Chain dashboard shows the status of all monitored units (cold rooms, freezers, fridges) at a glance.

KPI cards

Metric Meaning
Total Units Number of assets being monitored for temperature
Units OK Assets within their configured threshold
Units in Alarm Assets with a current temperature violation
Violations Total threshold breaches in the selected time range
Stability Score 0–100 score based on how consistently temperatures stay within range
Compliance Rate Percentage of time all units were within threshold

Unit status grid

Below the KPIs, each monitored unit shows a color-coded status card:

  • Green — temperature is within the configured threshold
  • Red — temperature is outside the threshold (alarm)

Click any unit card to see its detailed temperature history.

Tabs

Overview

The main tab showing all unit statuses, the violation summary, and trend charts.

Predictive Analytics

Uses historical data to identify:

  • Stability trends — is temperature getting more or less stable over time?
  • Deviation analysis — compares the last 24 hours against the 7-day baseline
  • Risk levels — flags units as Normal, Medium, or High risk

Compliance Report

A HACCP-style daily compliance view:

  • Shows pass/fail status for each unit per day
  • Exportable to CSV for regulatory documentation
  • Covers the selected time range (7d, 30d, 90d)

Setting up temperature monitoring

Step 1: Deploy sensors

  1. Attach an EverTag T sensor to each cold room, freezer, or fridge
  2. Configure the sensor using the CB Admin mobile app (NFC tap)
  3. The sensor auto-discovers via the Wirepas mesh and appears in TagFinder

Step 2: Create assets

  1. Go to Assets > Create Asset
  2. Name it (e.g., "Freezer 1 — Kitchen")
  3. Set the type (e.g., "Freezer" or "Cold Room")
  4. Assign the EverTag T sensor tag to this asset

Step 3: Set temperature thresholds

  1. Go to Alerts > Create Rule
  2. Set trigger type to Sensor Threshold
  3. Configure:
    • Field: temperature
    • Operator: greater than
    • Threshold: your upper limit (e.g., 8°C for a fridge, -18°C for a freezer)
  4. Add a second rule for the lower limit if needed (e.g., temperature < 2°C)
  5. Set recipients (email and/or SMS)

Step 4: Monitor

  • Check the Cold Chain dashboard daily for the compliance overview
  • Respond to alerts immediately — a temperature excursion in a cold room can mean spoiled goods
  • Export compliance reports monthly for HACCP documentation

Sensor data

Each EverTag T sensor reports:

Sensor Unit Precision
Temperature °C 0.1°C
Humidity %RH (if supported by model)
Battery voltage V Used for battery life monitoring

Data is stored for 90 days at full resolution, and 2 years in aggregated form.

Tips

Placement

Place sensors at product level, not on walls or ceilings. Temperature varies significantly within a cold room — measure where it matters.

Multiple sensors

Large cold rooms benefit from 2–3 sensors to catch hot spots near doors or defrost cycles.

Power outages

EverTag sensors and Wirepas mesh anchors are battery-powered. Monitoring continues during power outages — this is a key advantage over Wi-Fi-based systems.
